technetium star

== English == === Noun === technetium star (plural technetium stars) (astrophysics) A star in which technetium has been detected. Technetium is too short-lived to occur primordially in the star, if the star is about 4.5 billion years old (the estimated age of the Earth), so the star must be producing technetium. ==== See also ==== Przybylski's Star
